Contains accessibility and keyboard navigation specification of Telerik and Kendo web components.

Out of the box, the {{ site.product }} RadioGroup provides extensive accessibility support and enables users with disabilities to acquire complete control over its features.


The RadioGroup is compliant with the [Web Content Accessibility Guidelines (WCAG) 2.2 AA](https://www.w3.org/TR/WCAG22/) standards and [Section 508](https://www.section508.gov/) requirements, follows the [Web Accessibility Initiative - Accessible Rich Internet Applications (WAI-ARIA)](https://www.w3.org/WAI/ARIA/apg/) best practices for implementing the [keyboard navigation](#keyboard-navigation) for its `component` role, provides options for managing its focus and is tested against the most popular screen readers.

## WAI-ARIA


This section lists the selectors, attributes, and behavior patterns supported by the component and its composite elements, if any.

| Selector | Attribute | Usage |
| -------- | --------- | ----- |
| `.k-radio-list` | `role=radiogroup` | Announces the `radiogroup` role of the element. |
| `.k-radio-item` | `role=none` | Due to issues with nested items, forces a no-role state. |
| `.k-radio` | `readonly` or `aria-readonly` | The attribute is rendered only when the radio button is read-only. |
|  | `aria-invalid=true` | The attribute is rendered only when the radio button is in a `form` HTML element and announces the invalid state of the component. |
| `.k-disabled > .k-radio` | `disabled` or `aria-disabled` | The attribute is rendered only when the radio button is disabled. |
